WIRE-STRAIGHTENER.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application led June 4, 1918. Serial No. 238,193.

To all trimm, it may concern.'

Be it known that I, ToRvAL E. VIK, a citizen of the United States,residing at Shelton, in the county of Fairfield and State ofConnecticut, have invented new and useful Improvements inWire-Straighteners, of which the following is a specification.

This invention comprehends generally improvements in that class ofinventions known as wire working machines and more particularly hasreference to a wire straightener.

It is the primary aim and object of the present invention to provide adevice of the above mentioned character designed for straighteningpieces ot wire of various thicknesses.

It is an equally important object of this invention to provide a deviceof the above mentioned character wherein the main frame is of a novelform and is designed to removably receive and adjustably accommodate aseries `ot' supporting disks through which the wire is drawn when thetrame revolves.

More particularlyY the present invention includes the provision oi' aseries of supporting disks constructed to adjustablyv accom modate thewire receivin sleeves, suitable clamping means being incidentallymounted in the disks for holding the sleeves in a set position.

It is the m-ore specific object of this invention to provide improvedmeans for removably holding the disks in position in the frame; and alsoprovide improved means tor rotatably mounting the frame,

Among the other aims and objects of this invention may be recited theprovision of a device of the character described with a view tocompactness, and in which the number of parts are few, the constructionsimple and the cost of production low and the ei'- iiciency high.

Other improvements and novel details in the construction and arrangementof the various parts oi the apparatus will he brought out more in detailin the description to follow, which for a clear understandingof theinvention should be considered in connection with the accompanyingdrawings forming a. part hereof, and wherein is disclosed for thepurpose of illustration a cenvenient and satisfactory embodiment of theinvention. It is to be noted in this connection that minor changes inthe construction and arrangement of parts may be made without departingfrom the principle of operation ot' the various parts.

The invention is clearly illustrated in the accompanying drawings, inwhich:

'Figure 1 is a perspective view of the device.

Fig. 2 is a longitudinal sectional detail thereof.

Fig. 3 is a transverse section of the invention, and.

Fig. 4 is a detail of the adjustable clamping means.

Similar characters of reference are employed in all of the abovedescribed views to indicate corresponding parts.

Refcrrin now, more particularly, to the accompanying drawings, there isrovided a base 1 on the upper surface an near'the respective ends ofwhich are connected standards 2, the latter terminating at their upperends in bearings 3 while detachably connected to and coperating with thebear ings are bearing brackets 4.

A main supporting frame 5 is now employed and is of a substantiallyrectangular configuration comprising spaced side bars and curved ends 7,the latter having sleeves 8 connected thereto and extending in oppositedirections therefrom serving in effect as substantial trunnions andbeing journaled in the bearings 3 beneath the brackets. The sides 6 aredesirably arcuate in conguration and provide in effect opposed channels9 and these channel shaped sides are formed near the ends with opposedtransverse grooves 10. The channel shaped sides are provided withlongitudinal series of opposed openings 11 also for a purpose that willbe described.

Insertible in the opposed grooves 10 and receivable in the opposedchannel shaped sides of the frame is a plurality of disks 1:2 each ofwhich is formed with a radiai siot i3 and also with alining threadedbores li and l5 which establish communication with the respective endsof the slot and the outer edge of the disk.

The improved means tor holding the disks within the frame consists of aplurality of set screws 16 which are adjustably mounted in the opposedopenings 11 while the inner ends thereof are designed for frictionalengagement with the peripheries of the disks.

With a view toward providing suitable wire receivin means a pair ofrelatively long tubes 1 are telescoped within the sleeves 8 andremovably clamped in a set position by means of screws 18. Coperatingwith the tubes 1.7 are a series of smaller or relatively short tubes 19one ot' which is mounted in each ot the disks 1Q.

For the purpose ot' clamping the tubes 19 in the disks a pair ot opposedjaws 20 is disposed in each slot 13, the stems 21 of the jaws beingjournaled in circular recesses 22 formed in the adjacent ends ofexteriorly threaded screw plugs 23, the latter beingin turn adj ustablymounted in the threaded bores 1l and l5. The outer ends of the plugs 23are provided with kerfs 24 adapted to receive a screw driver or the likeso as to Jfacilitate adjustment of the plugs relative to each other andconsetpient clamping of the adjacent tube 19 in a relatively rigidposition with respect to the jaws 20.

The frame holding the disks is rotated by means of a sheave pulley 2over which a suitable belt may be trained and driven Jfrom a suitablesource of power not shown.

In the use of the invention, the number of disks employed may be variedto suit the character of bend in the wire to be straightened. To varythe spacing between the disks, one or more disks may be omitted, forexample the two disks on opposite sides of the center disk. The tubes 19in the outermost disk are preferably alined with the tubes lT andalternate disks between the two outside also have their tubes 19preferably alined with the tubes 1T and offset from the axis ot thetubes '17 respectively. The distance the offset tubes 19 are positionedfrom the centers of their respective disks is determined by the elasticlimit of the wire to be straightened. These offset tubes should not bepositioned a distance from the center oi" the disks greater than thiselastic limit. lt is obvious that the screw plugs 24 provide for theadjustment of the tubes 19 so that they may be eccentrically disposed intheir respective disks. The rotation of the frame by means of thepulley, after wire has been passed through the tubes 17 and through thetubes 19 in the several disks e'ects a distortion of the wire which isonly temporary on that part ot the wire not already having a permanentbend. This because the distortion is not greater than the elastic limitof the wire. Immediately a piece of wire containingr a permanent bendpasses through the tubes, the distortion on this particular part of thewire is greater than the elastic limit and the bent portion of the wireis thus brought back to normal shape.

Having thus fully described the invention what is claimed and desired tobe secured by Letters Patent is:

A wire straightener comprising an open frame embodying spaced parallelsides and ends, sleeves axially alined and projecting in oppositedirections from the said ends, supports ,in which the sleeves arerotatably mounted, a plurality oi disks carried in the frame andremovably secured therein by means which hold them in spaced relation,each disk being formed with a radial slot beginning at the center of thedisk and terA minating near the periphery, threaded plugs inserted inthe disks on diametrically opposite sides, the said plugs being radiallydisposed and alined with the slots, jaws mount ed in the slots andprovided with Shanks pivotally engaging in sockets formed in the plugs.wire receiving tubes carried between the jaws and disposed in the slots,and tubes removably mounted in said sleeves, whereby the first saidtubes may be thrown out ot' axial alinement with the last said tubes forthe purpose specified.

ln testimony whereof l affix my signature.
